Im trying to do all this by myself, so I can get the ball rolling, and still have money in my pocket, because the money i would pay for some one to all this, is going to pay off my junk ripped off tranny

Dude, I thought I answered this for you ?

To remove the valve springs you need a valve-spring-compressor. It looks like a big C-clamp with a fork on one end. You slide the fork end over the spring retainer and the other end presses against the valve on the chamber side. You crank it down until the locks come free and release the tool. Springs ensue.

In order to cut your heads for larger springs you need a spring seat cutter. Both Comp Cams and Crane make them. Get the tool that matches your spring diamteter and an 11/16"arbor to fit the valve guide. Attach the cutter to the arbor and the whole shebang to your drill. Slide it into the valve guide to keep the cutter steady and perpendicular to the seat (if your valve guides are crappy, don't even bother doing this. Get new valve guides first and cut the seats after). Add plenty of lube. The tool will cut the valve guide boss first and eventually the seat. You need to measure carefully once you get to the seat to make sure you don't cut too far past your springs recommended install height. A spring height micrometer is useful for that.

If you need to cut down the actual valve guide for higher lift clearance, you need a valve guide cutting tool, also sold by the aforementioned companies. Make sure you get new valve seals (positive style Viton or Teflon) in the same size as the tool. The process is the same as cutting the seats. Drill a little and measure a lot.
